TOC Analyzer and Control System

Measuring TOC (Total Organic Carbon) continuously online is the perfect solution for monitoring contamination and discharge in water. The system measures the total organic carbon in liquid samples, by using the method of UV persulfate oxidation with subsequent carbon dioxide detection. This is achieved via non-dispersive infrared absorption (NDIR). The analyzer can measure TOC in liquid samples ranging from 0–5 ppm to 20,000 ppm, and conforms to EPA, DIN, CE, ASTM, and NAMUR regulations as well as meeting the requirements of ISO and EN directives.

Safe and Reliable Online TOC Measurements – Separate lines are used for stripping gas and carrier gas. There are two separate gas lines, each with its own compressor. One is intended for the stripping gas for the TIC (total inorganic carbon) and one for the carrier gas which is automatically monitored by a digital flow meter.
Integrated carrier gas – An internal air compressor produces the carrier gas for the oxidation and detection stages. The air is purified using an internal soda lime filter, which means that there is no need for external air treatment or a compressed air supply, as in traditional analyzers.
Autoclean – This function uses a dedicated peristaltic pump to clean the liquid lines of the analyzer, the sample line, and the external reservoir.
